This study aims to develop a method of change detection and updating for urban building features at smaller-scale maps from updated larger-scale maps.Firstly,an in-deeper and comprehensive analysis of changes between maps at different times and scales was discussed.Then,a technical framework of change extraction and updating was proposed based on the functions of map overlap and data enrichment.Finally,real-life data were used to verify the effectiveness of the proposed method,and results also showed that our method is flexible and suitable for layer-level updates.
